PIrn-REAM'ING ivracnlvn.v f i To all whom t may concern.' y v Be it known that I, HENRY HILLEGASS, a citizen of the United States, residing at Houghton, in the county of Houghton and State of Michigan, have invented new and useful Improvements in Pipe-Reaming Machines, of which the following is a specification. l i rlhe invention relates to a Akpipe vreaming machine, in the use of whichpipes of varying diameters may be quickly and properly reamed. 4 Y f 1 The main object of the presentinvention is the provision of a machine adapted to be operated by hand and capable of tightly se-V curing the pipe section in position to permit coperation of the appropriate reamer therewith. j

The invention in the preferred form of details will be described in the'following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view in elevation of the improved machine. Fig. 2 is a front elevation of the same. Fig. 3 isa longitudinal central section. Fig. 4 is a transverse section on the line 4 4 of Fig. 1. Fig. 5 is a section on line 5 5 of Fig. 1.`

Referring particularly to the accompanying drawings, the improved machine includes a frame l formed to provide a rectangular chuck receiving section 2 having a pipe receiving aperture 3 in one face thereof. In the opposing end of the chuck section 2 of the frame are mounted shafts 4 reversely threaded at their respective ends. One end of the chuck section 2 is provided with a case 5 kinto which the ends of the shafts 4 extend, and in the case on said shafts are fixed pinions 6. A drive pinion 7 is mounted in the case having projecting a stem or stub shaft 8 adapted to be operated by hand in any suitable manner, the pinion 7 meshing with one of the pinions 6 and operating from a pinion 6 and through an intermediate pinion 9, whereby the said pinions 6 are simultaneously and similarly operated. The shafts 4 are arranged 1n the chuck section of the frame so that a similar n threaded portion of the respective shafts are opposite each other, and on the threaded portions of what may be said to be the upper parts of said shafts is mounted a chuck member involving a V-shaped jaw 10 projecting from a cross bar 11 terminating in threaded members 12 engaging the appron Specification of Letters Patent.v Patented luay 4, 19175.

priate parts of the shafts 4. Any opposing chuck member is arranged on the remaining portions ofthe shafts involving an angular jaw 13 projecting from a bar 14 terminating in members 15 havingv threaded coperation with the-shafts. V'F rom this construction it e j will be obvious thatA the chuck members may befcausedto approachor recede from.eachr said section 16' being cylindrical and con- 1 f stituting `a *bearing* section. Anoperating member isk rotatably mounted on the bearing section including a plate 17 having an annular flange 18 tov overlie Vand bearlupon; the

outer surface of the section 16. The-flange 18 is provided with removable rollers 19 seating in recesses 20 in the section 16, constituting a connection between the sections 16 and 17, and over an anti-friction bearing between the sections, though additional roller bearings are contemplated for such purpose if desired. The plate 17 is centrally formed with a rearwardly extending sleeve like member 21 constituting the hub, and a shaft 22 is mounted for sliding movement in the hub, having an ordinary sliding key connection 23 therewith. The inner end of the shaft 22 is of conical formation, as at 24, and removably secured upon the conical section of the section shaft is a reamer 25 which may be of any approved type. The shaft 22 extends beyond the hub 21 and is provided with a cap 26 connected through the medium ofv a screw 27 with the shaft, the cap being rotatable independently of the shaft but held against independent motion other than such rotation. The cap overlies From the above construction, it is obvious that the pipe section of any length or any h sion, an operating member yrotatably mountaimera?" Within the limits of ai@ Chuck' members, may be secured in position in the chuck section of the frame, and properly reamed by the rotation of the handle 31.

The reamer may be removably secured to the shaft vportion 24 so that reamers of different sizes may be used by a particular reamer removed for resharpening and the chuck members may be adapted in any convenient manner to receive padding strips y(not shown), whereby the original size may means foi' moving said chuck jaws toward and from each othera reamer shaft mounted for sliding and rotating movement in the frame, a nut secured to said shaft and having threaded connection with a portion of the frame,a reamer mounted in the shaft, and ymeans for rotating the shaft.

2. A reaming machine includinga frame, opposing chuck jaws operable in one portion of the frame, a cylindrical frame eXteners carried by the flange adapted to be seated in recesses in the bearing section and formlng a connection between the fiange and the bearing section, means for rotating the plate and the annular flange, a hub projecting f from the plate, a reamer shaft mounted for longitudinal movement in the hub, and a cap having threadedconnection with the hub.

In'testimony whereof I aiiiX my signature in presence of two witnesses.
